<h1 id="HISTORY">HISTORY</h1>

<p>Initially, the manual page entry for the <code>openssl <i>cmd</i></code> command used to be available at <i>cmd</i>(1). Later, the alias <b>openssl-<i>cmd</i></b>(1) was introduced, which made it easier to group the openssl commands using the <a href="../man1/apropos.html">apropos(1)</a> command or the shell&#39;s tab completion.</p>

<p>In order to reduce cluttering of the global manual page namespace, the manual page entries without the &#39;openssl-&#39; prefix have been deprecated in OpenSSL 3.0 and will be removed in OpenSSL 4.0.</p>
